Comment commenter les paramètres de pydoc
Existe-t-il un moyen de commenter les paramètres d'une fonction pour les faire reconnaître par la bibliothèque pydoc?
c'est-à-dire quelle est la docstring pour pydoc?
pydoc ne reconnaît pas les éléments "structurés" dans les docstrings, il sort juste la docstring telle quelle. Voir PEP-257 pour un exemple.
Si vous voulez une documentation "formatée", vous devez utiliser un autre générateur de documentation, comme Sphinx ou pdoc , par exemple.
Les paramètres des fonctions doivent être documentés dans la docstring des fonctions. Voici un exemple tiré de cette réponse :
"""
This example module shows various types of documentation available for use
with pydoc. To generate HTML documentation for this module issue the
command:
pydoc -w foo
"""
class Foo(object):
"""
Foo encapsulates a name and an age.
"""
def __init__(self, name, age):
"""
Construct a new 'Foo' object.
:param name: The name of foo
:param age: The ageof foo
:return: returns nothing
"""
self.name = name
self.age
def bar(baz):
"""
Prints baz to the display.
"""
print baz
if __name__ == '__main__':
f = Foo('John Doe', 42)
bar("hello world")
Voici un autre exemple plus explicite si vous souhaitez profiter d'un texte restructuré avec plus de descripteurs de paramètres, tels que :type param: ou :rtype: pris d'ici

The ``obvious`` module
======================
Use it to import very obvious functions.
:Example:
>>> from obvious import add
>>> add(1, 1)

.. warnings:: This is a completly useless function. Use it only in a
tutorial unless you want to look like a fool.

Vous pouvez également utiliser différents formats de docstring (comme Google ou Numpy ), que je recommande !!! pour rendre vos docstrings plus clairs.
J'espère que cela t'aides!
